Returns both GET and POST parameters in a single hash.
# File lib/action_dispatch/http/parameters.rb, line 13 def parameters @env["action_dispatch.request.parameters"] ||= begin params = begin request_parameters.merge(query_parameters) rescue EOFError query_parameters.dup end params.merge!(path_parameters) params.with_indifferent_access end end
Returns a hash with the parameters used to form the path of the request. Returned hash keys are strings:
{'action' => 'my_action', 'controller' => 'my_controller'}
See symbolized_path_parameters
for symbolized keys.
# File lib/action_dispatch/http/parameters.rb, line 43 def path_parameters @env["action_dispatch.request.path_parameters"] ||= {} end
The same as path_parameters
with explicitly symbolized keys.
# File lib/action_dispatch/http/parameters.rb, line 33 def symbolized_path_parameters @symbolized_path_params ||= path_parameters.symbolize_keys end
Convert nested Hash to HashWithIndifferentAccess and UTF-8 encode both keys and values in nested Hash.
TODO: Validate that the characters are UTF-8. If they aren't, you'll get a weird error down the road, but our form handling should really prevent that from happening
